A partner can almost always leave. Section 602(a) of the Uniform Partnership Act (1997) gives every partner the power to dissociate at any time, rightfully or wrongfully, by simply telling the partnership so. What that power does not guarantee is a clean exit: whether leaving breaches the agreement, what the leaving partner is owed, and how long their name stays attached to the business's debts are three separate questions the statute answers differently, and a partner planning to leave should know the answer to all three before saying anything.

The short version: leaving is rightful unless the agreement says otherwise or the partnership has a fixed term still running, the leaving partner is normally owed a buyout at fair value, and liability for what the business does afterward follows the leaving partner for up to two years unless they file a notice that cuts it off early. Each of those has an exception, covered below.

Rightful dissociation versus wrongful dissociation

In a partnership at will, which is most partnerships with no end date written into the agreement, giving notice to leave is rightful by default. Section 602(b) narrows wrongful dissociation to two situations: leaving in a way that breaks an express term of the partnership agreement (a notice period the agreement requires and the partner skipped, for instance), or, in a partnership formed for a definite term or a particular project, withdrawing by express will before that term or project is finished. A handful of exceptions inside 602(b)(2) excuse an early withdrawal that follows closely after another partner's death, bankruptcy, or wrongful exit, or that happens under specific forced circumstances like the partner's own bankruptcy.

The difference is not academic. A partner who wrongfully dissociates is liable to the partnership and the other partners for the damages that dissociation causes (section 602(c)), on top of whatever else they already owed, and if the partnership has a fixed term still running, that partner cannot collect any part of their buyout price until the term or project would have ended anyway, unless a court finds early payment would cause no undue hardship to the business (section 701(h)). A partner leaving a term partnership early should expect to wait for their money, not negotiate around it.

What leaving costs, by partnership type

Partnership at will Partnership for a definite term or project
Is leaving on notice a breach? No, unless the agreement sets a different rule Yes, if it happens before the term ends or the project is finished
Damages owed for leaving None, if rightful Yes, if wrongful: offset against the buyout price
When the buyout is paid Normal buyout timeline (120 days after written demand, or an agreed schedule) Not until the term or project would have ended, unless early payment causes no undue hardship
Can the partnership keep operating? Yes, almost always, with a buyout of the leaving partner Yes, if at least half the remaining partners choose to continue rather than wind up

Leaving a partnership, in order

Steps for the partner who is leaving

  1. Read the agreement's withdrawal and buyout clauses first

    A written agreement usually sets its own notice period, valuation method and payment schedule, and those govern over the statute's defaults. If there is no agreement, or it is silent, the defaults below apply.

  2. Decide whether leaving now is rightful

    Check whether the partnership is at will or has a definite term or project still running, and whether the agreement sets its own notice requirement. Leaving a term partnership early, or breaking a notice clause, is wrongful and carries damages.

  3. Give written notice of the express will to withdraw

    Dissociation happens once the partnership has notice (section 601(1)). Put the date in writing and keep proof it was received; the date of notice is also the date the buyout price and interest start running.

  4. Demand the buyout in writing

    The 120-day clock for the partnership to pay or offer to pay runs from a written demand (section 701(e)), not from the date of dissociation. A partner who does not demand payment can be left waiting indefinitely.

  5. File a statement of dissociation

    Filing starts a 90-day clock after which third parties are deemed to know the partner has left (section 704(c)), cutting off new liability sooner than simply waiting out the two-year default.

  6. Tell the people the leaving partner personally dealt with

    The 90-day filing protects against people who never check the public record; it does not replace telling the bank, major suppliers and regular customers directly, since actual notice ends exposure to them immediately.

  7. Resolve non-compete and confidentiality terms before signing anything

    A buyout agreement often adds new restrictions beyond what the partnership agreement already had. See non-compete rules after a business partnership ends before agreeing to new terms in exchange for payment.

  8. Get the buyout price and payment terms in writing, and get paid

    Interest accrues from the date of dissociation to the date of payment. A partner who waits to formalize the amount owed is giving up interest they are statutorily owed.

What a leaving partner is actually owed

Where the business continues without the leaving partner, section 701 entitles that partner to be bought out, not simply to walk away with nothing. The price is what they would have received if, on the date they left, the firm's assets had been sold at the greater of liquidation value or the value of the whole business as a going concern without them, with interest running from that date to the date of payment. If the partners cannot agree on a number within 120 days of a written demand, the partnership has to pay its own estimate; the leaving partner can then sue within statutory time limits to have a court set the real figure, with the partnership bearing the cost of an unreasonable refusal to pay or disclose. Anything the leaving partner owes the partnership, including wrongful-dissociation damages, is subtracted from that number before payment.

An LLC member leaving under the harmonized uniform LLC act gets none of this by default. Without a buyout right written into the operating agreement, a departing member becomes a mere transferee of their own economic interest: a claim on distributions if and when the LLC ever makes them, with no vote, no buyout, and no deadline for anyone to pay them anything. This is one of the starkest differences between the two kinds of entity, and it is why writing a partnership exit clause before you sign exists: an LLC operating agreement that is silent on exit has, in effect, written out the one protection a departing general partner gets automatically.

Negotiating the exit, not just litigating it

Most partners who are leaving are not trying to collect a statutory minimum; they are trying to get a fair number faster than the 120-day process and without a lawsuit over it. What gives a leaving partner weight in that conversation is the law in the background, not the first move. A partner who can accurately state what section 701 entitles them to, and who has already filed or is prepared to file a statement of dissociation, is negotiating from a position the other side cannot simply ignore. The partner who is staying has an incentive to settle fast too, since the two-year liability tail runs against the business, not just the person leaving, and an unresolved exit is a standing risk to anyone the firm deals with in that window.

Where the relationship has already soured to the point that talking is hard, how to tell your business partner it's not working covers the conversation itself, and mediation vs arbitration for a business partner dispute covers getting a neutral person to help set the number without going to court. A partner leaving a joint venture or strategic alliance rather than a true partnership should read when startups should walk away from a partnership instead, since the exit mechanics there often run through the venture agreement rather than a partnership act.

This is general information about the uniform partnership act and a harmonized state LLC act, not legal advice for a specific agreement. A lawyer in the partners' state should read the actual agreement and the state's own statute before anyone signs an exit.
